Pancreatic cancer was not included, \* intraoperative massive bleeding in 3 cases, PDJV; proximal-dorsal jejunal vein, TMpE; total mesopancreas excision, SMA; superior mesenteric artery. did not describe the R0 resection rate among the patients with this technique, and no patients with pancreatic head cancer were involved.

**Figure 2.** Intraoperative usage of indocyanine green (ICG) during obtaining the retroperitoneal margin of the pancreas*.* The ICG stained area is part of the uncinated process (**a**), which can be differentiated from the SMA to obtain the retroperitoneal margin (**b**). It can help the surgeon design surgical dissection. Note soft tissue around the SMA (retroperitoneal margin) is not stained by ICG.
